** ~~~ ** CheckCurveLimitsForStandardRatings: The max and/or min limits specified in the corresponding curve objects
It is the curves max/min values that are out of range.
Curve:Biquadratic,
17.22, !- Minimum Value of x
29.44, !- Maximum Value of x
18.33, !- Minimum Value of y
35, !- Maximum Value of y
The values used in these curves are based on the manufacturers data used to regress the coefficients. It is usually OK to somewhat widen the range. When users widen a range on a curve object (meaning the user is extrapolating performance) it is usually a good idea to plot the curve output to make sure the curves are smooth and reasonable.
hi ,
I want to know how to choose an adequate dx single speed coil from the ones available in data sets .
Whenever I choose a coil based on nominal amount of air and capacity I get this error message :
Warning ** The Standard Ratings is calculated for Coil:Cooling:DX:SingleSpeed = COIL_DX but not at the AHRI test condition due to curve out of bound.
** ~~~ ** Review the Standard Ratings calculations in the Engineering Reference for this coil type. Also, use Output:Diagnostics, DisplayExtraWarnings for further guidance.
** ~~~ ** CheckCurveLimitsForStandardRatings: The max and/or min limits specified in the corresponding curve objects
** ~~~ ** do not include the AHRI test conditions required to calculate one or more of the Standard Rating values.
** ~~~ ** Coil:Cooling:DX:SingleSpeed=COIL_DX: Integrated Energy Efficiency Ratio (IEER) calculated is not at the AHRI test condition.
** ~~~ ** Check limits in Total Cooling Capacity Function of Temperature Curve, Curve Type = BIQUADRATIC, Curve Name = YORK SUNLINE ZF240 CAPFT
** ~~~ ** Check limits in EIR Function of Temperature Curve, Curve Type = BIQUADRATIC, Curve Name = YORK SUNLINE ZF240 EIRFT
how can I solve that , and how can I identify each coil boundaries ?
